Artesyn Unveils SpiderWareSG High Density SIGTRAN Signaling Gateway

11/5/2003 - Artesyn Communication Products, a subsidiary of Artesyn Technologies (NASDAQ:ATSN), announced SpiderWareSG 2.0, a high-density SIGTRAN signaling gateway blade that enables SS7 signaling traffic to be transported over IP networks. Packaged in a CompactPCI Packet Switching Backplane (cPSB or PICMG 2.16) form factor, SpiderWareSG provides up to 64 SS7/SIGTRAN signaling channels with 80% line utilization, twice that of competitive solutions. This extraordinary line utilization and density enables telecom OEMs to build compact, low-cost signaling gateways that occupy less space and offer higher reliability than competitive gateways.

"SpiderWareSG provides an out-of-the-box SIGTRAN gateway for telecom OEMs who want to build reliable, high-density, low-cost signaling systems that bridge existing SS7 and next-generation IP networks," said Todd Wynia, vice president of marketing at Artesyn Communication Products. "SpiderWareSG provides twice the density and line utilization of competitive boards using small MSUs that better reflect real-world operating conditions. We expect SpiderWare SG to be very attractive to telecom OEMs who want to get to market quickly with best-of-breed signaling solutions."

Today's PSTN uses dedicated point-to-point networks to provide the SS7 signaling (Common Channel Signaling System No.7) needed for services such as call set up, teardown, routing, local number portability, call forwarding, and wireless PCS. SIGTRAN (Signaling Transport), a set of standards defined by the International Engineering Task Force (IETF), specifies a method for transporting SS7 signaling information over IP-based packet networks that enhances efficiency and flexibility while reducing cost.

SpiderWareSG provides a complete SIGTRAN signaling gateway on a single CPSB blade, enabling the PSTN network to connect to IP-enabled Signal Transfer Points, Service Control Points, Home Location Registers, Media Gateway Controllers, and Visitor Location Registers. Utilizing SIGTRAN's M2UA protocol, SpiderWareSG provides a transparent connection between the TDM-based SS7 network's MTP2 layer (data link) and the equivalent SIGTRAN layer (SCTP) on the IP side. SpiderWareSG is compatible with existing SS7 applications and requires no change to the SS7 network topology or reconfiguration of SS7 network elements.

SpiderWareSG provides up to 16 E1/T1 spans to communicate with the SS7 the network and a pair of Gigabit Ethernet links (accessed via the boards CPSB backplane) to communicate with the IP network. The gateway supports up to 64 SS7/SIGTRAN channels (SS7 to SIGTRAN and SIGTRAN to SS7) with 80% line utilization using MSUs (Message signaling Units) that are as small as 25 bytes. Competitive gateways must use much larger MSUs, which are not reflective of real-world operation, in order to achieve adequate line utilization.

SpiderWareSG provides a complete STREAMS-based implementation for SS7's lower-level MTP1 and MTP2 protocol layers, and SIGTRAN's SCTP and M2UA layers. Upper layer protocols such as MTP3, ISUP and SCCP are also available. The stack complies fully with ANSI, ITU, Telcordia, and IETF standards, and is interoperable at each layer with all industry standard implementations. The stack also comes with a PowerPC/Linux API, which may be run either on a separate host card or on SpiderWareSG's local PowerPC 750 processor.

SpiderWareSG combines an IBM 800-MHz PowerPC® 750FX host processor with up to two 300-MHz PowerQUICC II communications processors. The gateway complies fully with the PICMG 2.16 cPSB standard, an Ethernet-based interface for moving data between cPSB boards. SpiderWareSG also supports the PICMG 2.9 System Management Bus, which provides an I2C-based Intelligent Platform Management Interface (IPMI) that makes it easy to monitor, control and exchange management information between SpiderWareSG and shelf management controllers.

SpiderWareSG complies with all major safety, EMC, and environmental standards, including IEC60950/EN60950, UL60950, CSA C22.2, Global IEC - CB Scheme Report IEC 60950), NEBS Telecordia GR-63, and GR1089 Level 3, FCC Part 15 (U.S. and Canada), and ETSI EN300386-V1.3.1.

SpiderWareSG 2.0 is available immediately starting at $9000 in single-piece quantity.
